M71.029 Abscess of bursa, unspecified elbow

Name of the Condition

• Abscess of bursa, unspecified elbow

Summary

An abscess of the bursa, unspecified elbow is a localized collection of pus within the bursa of the elbow, a small fluid-filled sac that reduces friction between tissues. This condition typically causes pain, swelling, and warmth at the affected site. The unspecified elbow designation indicates the abscess is localized to the bursa in the elbow region without specifying left or right.

Causes

Abscesses of the elbow bursa usually result from bacterial infection, often introduced through direct trauma, skin breakdown, or spread from adjacent tissues. Staphylococcus aureus is a common causative organism. Non-infectious causes, such as foreign body reaction or sterile inflammation, are less frequent.

Risk Factors

• Recent injury or surgery near the elbow bursa
• Skin infections or open wounds in the elbow area
• Immunocompromised states (e.g., diabetes, HIV)
• Chronic inflammatory conditions (e.g., rheumatoid arthritis)
• Repetitive motion or pressure on the elbow bursa

Symptoms

• Localized pain, tenderness, or throbbing in the elbow
• Swelling, redness, or warmth over the bursa
• Limited range of motion in the elbow joint
• Possible fever or systemic signs if infection spreads
• Pus drainage if the abscess ruptures

Diagnosis

Diagnosis involves a physical examination to assess bursal swelling, warmth, and tenderness. Imaging (e.g., ultrasound) may be used to confirm the presence of an abscess. Aspiration of the bursa may be performed to identify the causative organism and guide treatment.

Treatment Options

Treatment typically includes antibiotic therapy for bacterial infections and drainage of the abscess, either through needle aspiration or surgical incision. Rest, elevation, and pain management may also be recommended. In severe cases, hospitalization for intravenous antibiotics may be necessary.

Prognosis and Follow-Up

With prompt treatment, most bursal abscesses resolve without long-term complications. Follow-up care may involve monitoring for recurrence or complications, such as chronic bursitis or infection spread. Physical therapy may be recommended to restore function if mobility is impaired.

Complications

Untreated abscesses can lead to the spread of infection to surrounding tissues or bloodstream (sepsis). Chronic inflammation or scarring may result in persistent pain or limited joint mobility. Rarely, surgical intervention may be required to address complications.

Lifestyle & Prevention

• Avoid repetitive pressure or trauma to the elbow
• Maintain good skin hygiene to prevent infections
• Use protective gear during activities that risk elbow injury
• Manage underlying conditions like diabetes or rheumatoid arthritis
• Seek prompt care for skin wounds near the elbow

When to Seek Professional Help

Consult a healthcare provider if you experience persistent elbow pain, swelling, or warmth, especially with fever or pus drainage. Immediate medical attention is needed if symptoms worsen rapidly or systemic signs of infection (e.g., chills, high fever) develop.

Tips for Medical Coders

Document the anatomical site (unspecified elbow) and confirm the presence of a bursal abscess. Ensure clinical documentation supports the diagnosis, including signs, symptoms, and any diagnostic procedures performed. Code M71.029 is specific to the elbow bursa without side specification; avoid using this code if the site is clearly left or right.
